Permeation Calibration

The PermaCal has been designed to easily generate different types of calibration gases like BTEX, Acetaldehyde, Formaldehyde, SO2,... Equipped with a large size permeation oven, the PermaCal can hold up to 6 permeation tubes with sizes going up to 12 cm length and 1 cm diameter. The oven temperature can be set from 40°C to 80°C. The concentration of the different components can be changed by a factor of 10 using the internal Mass Flow controller. The total flow of the system will be from 500 Nml/min for the high concentration setting up to 5000 Nml/min for the low concentration setting. The unit can also be used for diluting high concentration gas cylinders to the ppm and ppb level as well. A large number of permeation tubes are available. Each tube is delivered with its permeation rate certificate. Ideal for any kind of laboratory-made gas standard with different concentrations. LNI Schmidlin.
